First off, Oceanlab is a vocal trance group under Above & Beyond featuring vocalist Justine Suissa. They released Satellite in 2003. Since then it’s been remixed pretty heavily.

I also quite enjoy this version:
Arkasia released this first on Dubstep.net and he’s going to be releasing an EP on August 27. The details for that aren’t known. His New World Disorder is a favorite.
